Abstract:

Bio-fuels appear to be more environment friendly in comparison to fossil fuels, considering the emission of greenhouse gasses when consumed. In this paper, an attempt is made to study and compare the mechanical and volumetric efficiencies of bio-fuels, prepared from the blending of soya-bean and mustard oils with petrol. It is found that the out of the two soya-bean oil blends, 15-PRS shows the higher mechanical efficiency compared to 20-PRS at the engine loads of 2.5 Kg, 5 Kg and 7.5 Kg, while out of the two mustard oil blends, 20-PRM shows the higher mechanical efficiency compared to 15-PRM at the engine loads of 2.5 Kg, 5 Kg and 7.5 Kg. Out of the two mustard oil blends, 15-PRM shows the higher volumetric efficiency compared to 20-PRM at the engine loads of 2.5 Kg and 5.0 Kg.
